Pass clang flags to the host compiler, too.
Pass clang flags to the host compiler, too.

As of http://codereview.chromium.org/7471028, clang is used as
host compiler as well, so this check is no longer necessary. In
fact, it's harmful: In http://codereview.chromium.org/7550002 ,
a dependency on base is added on the host side, which doesn't
build with clang because e.g. -Wno-char-subscript isn't used,
which means base/third_party/dmg_fp/dtoa.cc doesn't build cleanly
in host compiler mode.
